Abstract

The isotropic quantum Heisenberg antiferromagnet at T equals 0 is studied using the renormalization group method for perturbation expansion of the Dyson-Maleev spin wave model in the inverse of the spin size S. The result does not agree with that of non-linear delta -model in two dimension.
